本文介绍的迫冷系统是没有膨胀机的一种系统,它可使超导磁体长期维持在4.5～5K 范围。对冷箱的试验表明迫冷质量流为6～10kg/h,对应的氦杜瓦中流出的液氦为1.1～1.3kg/h。
The forced cooling system introduced in this paper is a kind of system without expander, which can maintain the superconducting magnet in the range of 4.5 ~ 5K for a long time. The tests on the cold box showed that the forced mass flow was 6 ~ 10kg / h and the corresponding liquid helium in the helium dewar was 1.1 ~ 1.3kg / h.
